Abstract: A door handle includes a door handle case and an electrostatic sensor provided in the door handle case. The electrostatic sensor includes a detection electrode that is formed of a flat conductor plate, or that is formed on a surface of a flat substrate or within a flat substrate. The detection electrode includes a middle portion in a longitudinal direction of the detection electrode and includes peripheral portions proximal to both end portions of the detection electrode in the longitudinal direction. For a width of the detection electrode in a direction perpendicular to the longitudinal direction, each peripheral portion is wider than the middle portion, and the width of the detection electrode gradually increases toward each end portion in the longitudinal direction.

Abstract: An operation detection device includes an electrostatic sensor accommodated inside a casing and including a first conductor and a second conductor, and a controller electrically connected to the first conductor and the second conductor, and applies a voltage to each of the first conductor and the second conductor, to measure an electrostatic capacitance of each of the first conductor and the second conductor. The first conductor is arranged in and the second conductor is not arranged in a detection region in which an operating body is detected by the electrostatic sensor. The first conductor and the second conductor are arranged in a non-detection region in which the operating body is not detected.

Abstract: An input device includes a capacitive sensor and a piezoelectric sensor. The piezoelectric sensor is positioned on the front side of the capacitive sensor in a front-to-back direction from the front to the back of the input device, and is configured to change its output in response to a force applied to the piezoelectric sensor from its front side. The piezoelectric sensor includes a piezoelectric layer and a first electrode and a second electrode positioned across the piezoelectric layer from each other in the front-to-back direction. The capacitive sensor includes a capacitive sensing area where the capacitive sensor is configured to perform a sensing operation. The first electrode and the second electrode of the piezoelectric sensor do not overlap the capacitive sensing area when viewed in the front-to-back direction.

Abstract: A tire deterioration inferring (estimating) method uses a tire deterioration inferring device placed on the inner surface of a tire. The method has: a deformation velocity measurement step of measuring a tire deformation velocity, which is the deformation velocity of the tire while the tire is rotating, and obtaining time-series changes in the tire deformation velocity; a calculation step of calculating peak values of the tire deformation velocity from the time-series changes in the tire deformation velocity; and an inference step of inferring the degree of the deterioration of the tire by using a first peak value, which is a peak value of the tire deformation velocity before and at the stepping of the tire or at and after the kicking of the tire, the first peak value being in the time-series changes in the tire deformation velocity.

Abstract: A door handle includes door handle case, a first detection electrode and a second detection electrode disposed in the door handle case, and a controller connected to the first detection electrode and the second detection electrode. The controller separately measures a first capacitance between the first detection electrode and an operation body and a second capacitance between the second detection electrode and the operation body, and the controller determines whether a locking operation is performed by the operation body based on one or both of the first capacitance and the second capacitance.
